SLIDING STAPLE FOR HASPS.

SPECIFICATION forming part of Letters Patent No. 513,667, dated January30, 1894. Application filed June 24, 1893. Serial No. 478,762. (Nomodel.)

.To all whom t may concern:

Be it known that I, JOHN L. BUOKINGHAM, acitizen of the United States,residing at I-Iermosa, in the county of Custer and State of SouthDakota, have invented certain new and useful Improvements in SlidingStaples for Hasps, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in staplesfor use in conl nection with hasps, and it has for its objects amongOthers to provide a simple staple which will automatically accommodateitself to a hasp on a door when the door expands or contracts by theaction of the changes of the weather. It is a well known fact that if adoor be fitted with a hasp and a staple be arranged to co-operatetherewith, or if the door shrinks the hasp will not fit Over the staple,and the same result takes place should the door swell during wetweather. I propose to overcome this difficulty. I mount the staple toslide in a bearing which is fixedly secured to the support so that thestaple may automatically be moved as it is engaged by the hasp in anendeavor to close the latter over the staple, so that the hasp will beengaged with the staple no matter whether the door swell or shrink,without the necessity of withdrawing the staple from its support asheretofore.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claim.

The invention is clearly,7 illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure lis an elevation of my improvedstaple. Fig. 2 is a longitudinal section through the same on the line2-2 of Fig. l. Fig. 3 is a cross section thereof on the line 3 3 of Fig.l. Fig. 4. is a perspective detail showing the application of myimprovement.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates astaple which is fixed on a plate B.

C is a housing or support which is preferably formed of sheet metalfolded upon itself as seen best in Figs. 3 and 4 and provided with alongitudinal slot b as seen in Figs. l and u 4 through which the stapleis designed to project and slide freely. The ends Of the tubular part Care closed by filling pieces D as seen in Figs. l and 2, or they may beleft open if preferred. If filling pieces are elnployed they may be heldin position in any suitable manner. The plate B which carries the staple is of sufficient width to extend under the upper or outer wall ofthe part C suciently to prevent its displacement as shown in the variousviews so that while the staple is free to move lengthwise of the part Ostill it cannot become displaced.

In use the part C is secured to the door frame or other part or supportand the hasp afxed to the door in the usual manner. The staple beingfree to slide either way in its guide part O it will be readily seen howeasily the hasp can be engaged thereover no matter whether the doorswell or shrink. The parts will be as securely held as if the staplewere of the usual kind and ixed in its support.

WVhat I claim as new is` The herein described staple consisting of ahousing of sheet metal bent into the form of a tube and having alongitudinal slot, filling pieces in the ends of the tube, a plate heldwithin the tube to slide lengthwise thereof, and a staple secured tosaid plate with its legs passed through said slot and movable with theplate lengthwise of the tube, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN L. BUOKINGHAM.
